MATLAB: How to Plot Delay Differential Equations Graphic

ddedde graph

I need to draw a DDE graph for my homework. But I don't know how to draw. Can you teach me how to draw a DDE graph?

figure(1); x=[1 2 3 4]; y=[4 6 8 10]; plot(x,y);

figure(2); x=[0:0.1:10]; y=x.*x; plot(x,y);

Good luck

% doc plot
x = 1:10;
y = x.^3;
plot(x, y)
